Technical Field

[0001] The present invention relates to the technical field of adjustable wrenches, and more particularly to a reciprocating resettable adjustable wrench. Background Art

[0002] In today's industrial and life scenarios, the adjustable wrench is undoubtedly an extremely critical hand tool. With its feature of flexible adjustment of the jaw size, it has been widely penetrated into various fields such as auto repair workshops, factory assembly lines, home improvement construction sites, etc., providing convenience for the tightening and disassembly of many nuts and bolts. However, with the iteration of technology and increasingly complex practical scenarios, the shortcomings of traditional adjustable wrenches have become increasingly prominent, causing many troubles to users.

[0003] When a traditional adjustable wrench turns a nut, after it is turned to a certain angle, the wrench will be constrained by its own structure and the surrounding space and has to disengage from the nut. Only after the angle is readjusted can it be turned again. This intermittent operation is barely sufficient in an open area, but once it is placed in a narrow space, such as the inside of a car engine compartment or a corner of a factory equipment with dense pipes, it is necessary to constantly adjust the angle, wasting a lot of time and energy, causing time-consuming and inconvenience to the user's work, and lowering the overall satisfaction.
